Sydney Trains S set

In 1972 the first S set entered service to replace the steam and Diesel trains and possibly the U sets. And some of the Red 'Rattler's

Some Tulloch carriages were part of some trains, later in 2002, they were soon withdrawn and we're replaced by M sets.

Later by 2002 parts of the S sets, along with the K, C and T sets were painted yellow, as of 2010, this has been completed

By 2009 it was announced that the New A Sets were being delivered, Testing began in 2010 and the first Waratah entered service in 2011, as the New South West Raillink was being constructed, it was announced that some of the S sets would still be required to test on the line, there was an option to extend the order for the Waratahs, as The final A set was delivered, it replaced Two thirds of the S sets, the S sets now operate on sector 2 as Standbys.

In July 2017, asbestos was found under the brake panels in the driving compartment of the C and the K sets, the Asbestos caused all the C and K sets to be taken out service for inspection, that was time for the S sets to do the timetables marked as "C" and "K", later by the end of July, 2017, a few of the S sets were taken back to do shifts on the T7 line, meaning a few K and C sets returned to service, but many of them are still being inspected, by August, The C and K sets returned to service.

When A new Timetable was introduced in November 2017 lots of S sets were bought back permanently, especially on The Carlingford line. When The B sets enter service, The S sets will be likely to be bought back for The Olympic Park Shuttle. And completely withdrawn by 2023

Back in 2014, The NSW government announced that the remaining third of the S sets will no longer be running as some New Trains were announced for The NSWTrainLink network and will succeed the entire V set fleet and allow most of the H Sets onto the Sydney trains network to replace the Remaining third of the S sets.
